Combination Variable Frequency Drive

Control Speed and Save Energy with ABB Variable Frequency Drives

Variable frequency drives (VFD's) are used to control the speed of an AC electric motor. This is done by controlling voltage and frequency of power supplied to the motor. AC variable frequency drives can extend the motor speed range from zero to high above the rated speed, increasing the productivity of the driven process. When a low capacity is enough, the drive reduces the machine speed and lowers energy consumption. VFD's optimize power usage and thus save energy.

ABB variable frequency drives are the global reference that signifies reliability, simplicity, flexibility and ingenuity throughout the entire life-cycle of the drive.
